Filed: 1970-06-10
Abstract: 1300173 Evacuating aerosol dispensers COSTER TECNOLOGIE SPECIALI SpA 10 June 1970 [28 June 1969] 28167/70 Heading B8T [Also in Division F1] A device for evacuating aerosol dispensers, prior to filling, comprises an outer body having a tubular wall 1, disc 2 and resilient sleeve 10, and an inner body including a piston 3 and stem 4. The piston 3 can travel a distance defined by two stroke-end stops, one being the disc 2, and the other when the collar 9 on the stem 4 abuts the enlargement 8 of the wall 1. At rest, the piston and stem are held at their lower limit by a spring 20. The device is lowered on to the container 13 having a cap 12 with a dispenser 22 placed on top and separated from the container by a resilient gasket. The bottom of the stem 4 contacts the cap 12 and the outer body moves down so that the sleeve 10 forms a seal with the container 13, whereupon a suction pump is attached to the hole 17, and air supply means are connected to the hole 18. Thus the air is evacuated from the chamber 16, and the air pressure lifts up the piston 3. The region below the stem 4 is separated from the chamber 16 until the top of the groove 23 clears the gasket 15 (Fig. 4) when the cap 12 is lifted upwardly and the air is sucked out of the container and out through the hole 17. This continues until the pressure in the container is the same as that in the chamber 16 and the cap 12 falls back on the gasket on the container mouth. The air pressure to hole 18 is shut off and the spring 20 forces the stem 4 downwards, pressing the ring on to the gasket which is crushed, thus ensuring a tight fit. The device is then raised, whereupon the cap 12 is crimped on to the container 13 and it can then be filled by known means.

[Also in Group II] A rectifying and photo - sensitive element comprising a P-N junction is produced by heating one end of an N-type germanium specimen and cutting out the portion where the junction is produced. One end of the germanium strips 1 is placed between graphite blocks 2 and 3, and the other end is held in contact with a graphite plate 4. The assembly is placed in an evacuated envelope and current is passed through plate 4 to heat that portion of the germanium to 1000 C. while the other portion is maintained below 400 C. by blocks 2 and 3. After cooling, the junction is located by measurement of photosensitivity and that section removed. The ends of this section are nickel-plated and protected by an insulating varnish, and the section is then used as the anode in an electrolytic bath containing potassium hydroxide solution, an etching current of 1 m.a. being passed. The photo-sensitivity of the P-N junction is measured while the current is being passed, the process being continued until the sensitivity is a maximum. The section is then washed and dried, and coated with a thin protective insulating film of material such as " Araldite " (Registered Trade Mark) which is then cured. The Provisional Specification refers to the manufacture of an N-P-N junction unit by the above method.

Abstract: 357,775. Bottle-washing machines. FLOWER, A. L., Union Place, Marshall Street, Leeds. Sept. 23, 1930, No. 28482. [Class 138 (i).] A bottle-washing machine comprises a soaking tank 2, Fig. 1, containing a series of double tracks 1 of superposed rails alternately inclined in opposite directions so that flanged tubes 4 containing bottles can roll to the bottom of the track step by step. The bottommost tube 4 is removed by an endless conveyer 6 with cradles 7 when the tube is released by an oscillating stop 8. The conveyer is driven intermittently by a cross wheel 9 and some wheels not shown. The cradles on the conveyer are so spaced that when one receives a tube from the bottom of the track others are in register with scrubbers 15 and a shoot 16. The bottles in the tubes in register with brushes of the scrubbers are ejected into engagement with the brushes and those in register with this shoot are ejected into it by rams 18, Fig. 2, reciprocated by a crosshead 19. The crosshead is carried by two shafts 20 and comprises three fingers 21 and is reciprocated by an oscillating connecting-rod 23 operated as a disc 25. The bottles ejected to the scrubbers press at their mouths against bosses 28 on fingers 29 and cause the fingers to slide with shafts 20 against weights 30. As there are two scrubbers each bottle is scrubbed twice, thus enabling the output of the machine to be increased without loss of efficiency. Each scrubber consists of rotary brushes 33 for outsides of bottles and a long rotary brush 34 for insides. Scrubbed bottles are restored to their tubes by fingers 29. Bottles ejected into the shoot are delivered into rubber cases 35, Fig. 1, on a driving wheel 36 which drops them onto a conveyer.
